The MOC looks nice, some of the bare ball joints are a no-no, especiallt the one on the back of the neck, you could add hair to make it more feminine like. I see the hands and feet are small, which could reference feminine-physique, but there's not much else. I like the arms and the legs though, they look pretty well armored and stuff. Nice work.
I'll be honest, she really doesn't look like Takanuva or look feminine. The torso is too skinny, and you really can't see any definable feminine features present. Also, besides having the Avohkii and a staff, there's really no resemblance between her and Takanuva.
